About 7,500 people lost power after a tree fell bringing down electrical transmission cables, a PG&E spokesman said. It was not clear whether the downed lines started the fire or if the tree fell on the lines due to the blaze.

Crews were on the scene and had restored power to roughly half of the customers by 6:45 p.m. and estimated full restoration by the end of the night.

Cañada Road was closed at Godetia Drive and the California Highway Patrol issued a travel advisory for Highway 280 through Woodside due to heavy smoke. All lanes remained open, but traffic was heavy through the area, a CHP dispatcher said.
